An unusual, beautiful, pure white, semi-double form of C trachelium, reputedly first recorded 300 years ago and saved from extinction by a well known nursery in Wiltshire, England.

Does best in partial shade with dryish soil. Quite slow to increase but it has been very reliable for us over the last few years. For some reason this particular specimin attracts slugs while the type species just 3 feet away is rarely scoffed.

Not reliably true from seed!
